Didier Berthet

Didier Berthet (11 June 1962 – 8 September 2023) was a French Roman Catholic prelate who was bishop of Saint-Dié from June 2016 until his death. Raised as a Protestant, Berthet converted to the Catholic Church as a young adult after attending an event when Pope John Paul II was present in France in 1980. He was ordained a priest of the Roman Catholic Diocese of Nanterre in 1992 and in 2016 was named bishop of Saint-Dié.

Biography Conversion and Training Didier Barthet was born in Boulogne-Billancourt, Hauts-de-Seine to a Roman Catholic father and a Calvinist Protestant mother. He was baptized in the Reformed Church of France, receiving a Calvinist education. As a teenager, he attended the Saint Jean Hulst Catholic College in Versailles (1975–1980). At the end of high school, wishing to become a pastor, he reflected on what the Church is and came to the idea that the Catholic Church is apostolic, heir to the faith and succession of the apostles. In 1980, while Pope John Paul II was in France, he took part in a meeting with young people and discovered "the mystery of the Church around [the Pope], as a successor of Saint Peter and his person being the guarantor of a Church that comes from the origins of a universal Church". While studying at Sciences Po (1980–1983), he finally converted to Catholicism in 1983. He then entered the French seminary of Rome (1987–1993) and the Gregorian University of Rome (1987–1993), where he obtained a Bachelor's Degree in Theology (1991) and a Bachelor's degree in Canon Law (1993).
